      plat/arm: don't provide NT_FW_CONFIG when booting hafnium · 2b6fc535
      Manish Pandey authored
      
      
      NT_FW_CONFIG file is meant to be passed from BL31 to be consumed by
      BL33, fvp platforms use this to pass measured boot configuration and
      the x0 register is used to pass the base address of it.
      
      In case of hafnium used as hypervisor in normal world, hypervisor
      manifest is expected to be passed from BL31 and its base address is
      passed in x0 register.
      
      As only one of NT_FW_CONFIG or hypervisor manifest base address can be
      passed in x0 register and also measured boot is not required for SPM so
      disable passing NT_FW_CONFIG.

      SPM: declare third cactus instance as UP SP · e96fc8e7
      Olivier Deprez authored
      
      
      The FF-A v1.0 spec allows two configurations for the number of EC/vCPU
      instantiated in a Secure Partition:
      -A MultiProcessor (MP) SP instantiates as many ECs as the number of PEs.
      An EC is pinned to a corresponding physical CPU.
      -An UniProcessor (UP) SP instantiates a single EC. The EC is migrated to
      the physical CPU from which the FF-A call is originating.
      This change permits exercising the latter case within the TF-A-tests
      framework.

      plat/arm: fvp: Protect GICR frames for fused/unused cores · f98630fb
      Manish V Badarkhe authored
      
      
      Currently, BLs are mapping the GIC memory region as read-write
      for all cores on boot-up.
      
      This opens up the security hole where the active core can write
      the GICR frame of fused/inactive core. To avoid this issue, disable
      the GICR frame of all inactive cores as below:
      
      1. After primary CPU boots up, map GICR region of all cores as
         read-only.
      2. After primary CPU boots up, map its GICR region as read-write
         and initialize its redistributor interface.
      3. After secondary CPU boots up, map its GICR region as read-write
         and initialize its redistributor interface.
      4. All unused/fused core's redistributor regions remain read-only and
         write attempt to such protected regions results in an exception.
      
      As mentioned above, this patch offers only the GICR memory-mapped
      region protection considering there is no facility at the GIC IP
      level to avoid writing the redistributor area.
      
      These changes are currently done in BL31 of Arm FVP and guarded under
      the flag 'FVP_GICR_REGION_PROTECTION'.
      
      As of now, this patch is tested manually as below:
      1. Disable the FVP cores (core 1, 2, 3) with core 0 as an active core.
      2. Verify data abort triggered by manually updating the ‘GICR_CTLR’
         register of core 1’s(fused) redistributor from core 0(active).

      plat/arm: fvp: Do not map GIC region in BL1 and BL2 · e0cea783
      Manish V Badarkhe authored
      
      
      GIC memory region is not getting used in BL1 and BL2.
      Hence avoid its mapping in BL1 and BL2 that freed some
      page table entries to map other memory regions in the
      future.
      
      Retains mapping of CCN interconnect region in BL1 and BL2
      overlapped with the GIC memory region.

      Don't return error information from console_flush · 831b0e98
      Jimmy Brisson authored
      
      
      And from crash_console_flush.
      
      We ignore the error information return by console_flush in _every_
      place where we call it, and casting the return type to void does not
      work around the MISRA violation that this causes. Instead, we collect
      the error information from the driver (to avoid changing that API), and
      don't return it to the caller.

      'tpm_event_log_addr'

      and 'fvp_nt_fw_config.dts'. The node and its properties
      are described in binding document

      TF-A GICv2 driver: Introduce makefile · 1322dc94
      Alexei Fedorov authored
      
      
      This patch moves all GICv2 driver files into new added
      'gicv2.mk' makefile for the benefit of the generic driver
      which can evolve in the future without affecting platforms.
      
      NOTE: Usage of 'drivers/arm/gic/common/gic_common.c' file
      is now deprecated and platforms with GICv2 driver need to
      be modified to include 'drivers/arm/gic/v2/gicv2.mk' in
      their makefiles.

      plat/arm: Fix build failure due to increase in BL2 size · fdf50a25
      Manish V Badarkhe authored
      
      
      BL2 size gets increased due to the libfdt library update and 
      that eventually cause no-optimization build failure for BL2 as below:
      aarch64-none-elf-ld.bfd: BL2 image has exceeded its limit.
      aarch64-none-elf-ld.bfd: region `RAM' overflowed by 4096 bytes
      Makefile:1070: recipe for target 'build/fvp/debug/bl2/bl2.elf' failed
      make: *** [build/fvp/debug/bl2/bl2.elf] Error 1
      
      Fixed build failure by increasing BL2 image size limit by 4Kb.

      plat/arm, dts: Update platform device tree for CoT · 2a0ef943
      Manish V Badarkhe authored
      
      
      Included cot_descriptors.dtsi in platform device tree
      (fvp_tb_fw_config.dts).
      
      Also, updated the maximum size of tb_fw_config to 0x1800
      in order to accomodate the device tree for CoT descriptors.
      
      Follow up patch will parse the device tree for these CoT descriptors
      and fill the CoT descriptor structures at runtime instead of using
      static CoT descriptor structures in the code base.
